iPad: Now available to pre-order or reserve and pick up

Starting today the latest of apples mobile devices, the much hyped (magical and revolutionary) Apple iPad (Wi-Fi) is now available for online pre-ordering.  Starting today you can either order it online and have it delivered to your home or office on April 3 or you can reserve it and pick it up between 9:00 AM and 3:00 AM on April 3.

The iPad (Wi-Fi + 3G) is available for pre-order only and ships late April.  So the question is, do you get the Wi-Fi version now or wait for Wi-Fi + 3G and which memory option: 16GB, 32GB or 64GB?
